Summary of Mining Plans of Operation on
BLM Land:
Over 4,000 mining plans and notices, approval all but guaranteed under 132-year-old federal law
Jump to: Plan/Notice Owners | Claims | Patents | Map
Currently on file with the Bureau of Land Management (BLM) are 4,272 mining plans and notices filed by 489 companies and 432 individuals, encompassing a total estimated area of 185,513 acres of BLM-managed public land in The United States. These plans and notices are filed on public land laden with gold, silver, copper and other precious metals and minerals worth billions of dollars. And these operations are only those on BLM lands, not on Forest Service lands, for which mining plans and notices are not entered into the government's LR2000 database that forms the backbone of this site. But whether the mines are on BLM or Forest Service land, none of the corporate revenue is reimbursed to the public. Instead, companies leave behind unfathomable amounts of waste. In 2001 alone, the industry dumped enough mercury nationally to fill a billion thermometers and arsenic in quantities that would pollute all public drinking water supplies for 350 years. In 2001, mines generated 45 percent of all pollution reported in the U.S. while accounting for just 0.36 percent of all industrial facilities.
